12 months ago Hyperupdi has no expected release date and may not be further developed upon consideration of the fact that I have dozens of super critical things and this is an something I may not have time to ever implement. I work every waking g hour and fall further behind every day

Hi, I'd like to ask about the status of HyperUPDI http://../blob/master/UPDI/jtag2updi.md#hyperupdi.
I wanted to build a simple shield myself for Arduino Nano to extend jtag2updi with 12V booster and an opto-switch . But then I thought building a full one with a mCPU won't be much more complex. As you write, it'd allow both a pass-through and a buffered operation mode.
One possibility would be to use ATtiny322x https://ww1.microchip.com/downloads/aemDocuments/documents/MCU08/ProductDocuments/DataSheets/ATtiny3224-3226-3227-Data-Sheet-DS40002345B.pdf, which has 3kb of SRAM. I'm not sure if this would be large enough buffer. If not, it could be extended with a SPI external RAM chip.
Or, shifting the idea yet another level, one could use a Atmel SAM Dx https://ww1.microchip.com/downloads/aemDocuments/documents/MCU32/ProductDocuments/DataSheets/SAM-D5x-E5x-Family-Data-Sheet-DS60001507.pdf mCPU such as SAMD51J20. It'd have more than plenty of RAM and also has a built in USB interface. But obviously harder to program.
